For over 30 years, Dyrhoff has been a leading provider of water control gates, offering tailored solutions to meet any requirements.

Our specialty is in the design and supply of spillway gates and inflatable rubber dams. Since 1989, we've been involved in the rubber dam business, initially as the Scandinavian agent for Sumigate®, the world's leading supplier of inflatable rubber dams at the time. In 2003, we acquired the sole right to design and supply Sumigate® rubber dams worldwide from Sumitomo Electric, until they withdrew from the international rubber dam market in 2012.

Our own brand rubber dam was designed and supplied in 2007, using the design know-how originally acquired from Sumitomo Electric. All rubber dam components are designed and manufactured according to the latest Japanese technical standards, using a small number of experienced and reputable manufacturers and suppliers.

Dyrhoff is also the European agent for the Obermeyer Hydro Inc. (OHI) pneumatic spillway gate, which we have been selling in Europe since 1997. We supply complete spillway gate systems according to OHI's design and product specification, with rubber air bladders manufactured in the USA by OHI and other gate components manufactured in Europe by approved and experienced suppliers.

At Dyrhoff, we work mainly on a supply-only basis, but always provide on-site supervision to guide the installation contractor through the rubber dam or spillway gate installation, testing, and commissioning procedures.

We are committed to continuous improvement and innovation, with an active R&D program and patents for specific features of rubber dam design that can enhance performance. We also offer spillway gate products under our own brand and are in the process of developing new products for flood control and/or protection.
